Identify the set of reagents/reaction conditions X ad Y in the following set of tranformation `CH_(3)-CH_(2)-CH_(2)Broverset(X)to"Product"overset(Y)toCH_(3)-underset(Br)underset(|)(C)H-CH_(3)`A. X=dilute aqueous NaOH, `20^(@)C,Y=HBr//`acetic acid, `20^(@)C`B. X=concentrated alcoholic NaOH, `80^(@)C,Y=HBr`/acetic acid, `20^(@)C`C. X=dilute aqueous NaoH, `20^(@)C,Y=Br_(2)//CHCl_(3),0^(@)C`D. X=concentrated alcoholic NaoH, `80^(@)C` `Y=Br_(2)//CHCl_(3),0^(@)C`

Answer» Correct Answer - B
`CH_(3)-CH_(2)-CH_(2)Br underset(80^(@)(X))overset(alc." "NaOH)toCH_(3)-CH=CH_(2)underset("in "CH_(3)COOH,20^(@)C(Y))toCH_(3)-underset(Br)underset(|)(C)H-CH_(3)`.
